SPECIFICATION forming part of Letters Patent No. 599,494, dated February 22, 1898.

Application filed July 8, 1897. gerial N0. 6%,790. (N0 model.)

To aZZ whom it may concern/.-

Be it known that I, JULIAN L. Dono s, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented and produced new and useful Improvements in Meters, of which the following is a specification.

My invention relates to meters for measuring water and the like, and has for its object to provide a new and improved meter, of which the following is a description, reference being had to the accompanying drawings, wherein Figure 1 is a view in part section of a watermeter embodying my invention. Fig. 2 is a plan view of the disk of a water-meter shown in position. Fig. 3 is a section on line 3 3, Fig. 1, with parts omitted. Fig. 4 is a vertical section through a portion of the diskchamber of the meter, the disk being removed. Fig. 5 is a plan view of a portion of one of the end pieces of the disk-chamber.

Like letters refer to like parts throughout the several figures.

Disk'meters as heretofore constructed have been provided with a movable disk, usually of hard rubber and located in a disk-chamber provided with a division-plate, the disk being cut away or slotted to receive this divisionplate. It has been found in practice that the cutting away of this disk for the divisionplate weakens the disk to such an extent that it is often broken by the force of the water entering the meter. This breakage of the disk is particularly liable to happen after the parts have become somewhat worn, so that the contact of the disk with the division-plate produces a vibrating or chattering effect when the disk is moved.

One of the objects of my invention is to provide a disk-meter so constructed that the liability to breakage of the disk will be lessened.

Referring to the accompanying drawings, I provide a disk A of any suitable materialas, for example, hard rubber-provided with the ball-shaped central piece A and mounted in the disk-chamber A in the ordinary manner or in any other suitable way. The disk A is a continuous disk, the division-plate between the inlet and outlet of the meter being connected therewith. This division plate may be of any suitable material and may be constructed in any suitable manner. As illustrated in the drawings, said division-plate is provided with a curved edge B, preferably the arc of a circle. The division-plate is provided with some suitable guiding or holding device forholdingit against lateral movement. As illustrated in the drawings, the curved edge B of the division-plate works in a slot B in the disk-chamber or some part associated therewith. This division plate, as illustrated in the drawings, consists of two parts, one above and one below the disk, the parts being connected with the disk so that said disk is free to move with relation thereto. I prefer to have these parts of the divisionplate pivoted so as to rock or move about a center substantially in the plane passing through the middle portion of the disk.

As illustrated in the drawings, the disk A is provided with the projecting parts A so as to be formed thicker at the point where the division-plate is connected. These proj ecting parts are preferably rou nded,and the parts of the division-plate are formed so as to fit these rounded portions in order to make a comparatively tight joint. It is of course evident that the joint may be made in any other suitable manner. The parts of the division-plate, as illustrated in the drawings, are rigidly connected together by the pieces B said pieces being pivotally connected to the pin B located near the middle of the disk. The pieces B are held in place by means of the pins B By this construction the disk is free to move when the divisionplate is held against lateral motion. The cones or end pieces 0 of the disk-chamber are each provided with a slot O, through which the portions of the division-plate project as the plate is reciprocated by the movement of the disk. I prefer to form a separable disk-chamber, as shown, so that the disk may be easily placed in position. I also prefor to form the inlet and outlet passage-ways for the water in the walls of the disk-chamher, as illustrated at O in Fig. 2. The chambers D and D on each side of the diskcham her are preferably connected with the diskchamber or the inlet or outlet passage-waysas, for example, by openings 1) at the side of .in the working of the meter.

the disk-chamber-so as to equalize the pressure above and below the disk, the disk being suspended, as it were, in the water. The disk-pin E of the disk is connected with the meter-shaft E in the ordinary manner, so as to rotate the same, and bears against the cone E This cone E is elastically connected with the shaft E in any suitable manner, so that it may have a certain amount of lateral motion in order to prevent the binding of the parts when the shaft E is not accurately alined. This elastical connection may be formed in any convenient manner, and, as shown in the drawings, consists of an elastic washer E interposed between the cone and the shaft. It will be seen that by this construction as the disk A moves the division-plate, although held from lateral motion by its engagement with the meter-case, is so connected with the disk as to allow said disk to move with relation thereto and acts in all respects, so far as the operation of the meter is concerned, as though it were stationary and rigidly connected with the disk-case, the disk being cut away so as to receive it, as in the ordinary meter. It will also be seen that by this construction danger of the breakage of the disk by the impact or hammer of the water is greatly lessened, as the disk is continuous throughout and able to withstand any foroe which may be applied to it I have not illustrated the remaining mechanism of the meter for the reason that such mechanism is no part of my present invention and may be of any suitable description.

I have described in detail a particular construction embodying my invention in order to make its application clear; but I wish it to be understood that I in no manner limit myself to this particular construction, for it is evident that the construction and arrangement of the various parts may be greatly modified without in any manner departing from the spirit of my invention.

I claim' 1. A meter comprising a continuous disk, a disk-chamber in which said disk is movably mounted, said disk-chamber provided with an inlet and outlet for the fluid to be measured, and a division-plate interposed between said inlet and outlet.

2. A meter comprising a disk movably mounted in a disk-chamber, provided with an inlet and an outlet for the fluid to be measured, and a movable division-plate intermediate between said inlet and outlet adapted to be moved during the operation of the meter.

3. As an article of manufacture, a disk for I water-meters, comprising a disk proper adapted to be movably mounted in the meter-case, said disk provided with a reciprocating division-plate connected thereto, so as to move therewith.

4. As an article of manufacture, a disk for water-meters, comprising a disk proper adapted to be movably mounted in the meter-case, and a division-plate pivotally connected with said disk.

5. As an article of manufacture, adisk for water-meters, comprising a disk proper having a substantially continuous surface, a twopart division-plate, one part on each side of said disk, a connecting-piece passing through the disk and connecting the two parts of the division-plate together, said connecting-piece pivotally connected with the disk.

6. A meter comprising a movable disk, a disk-chamber in which said disk is mounted, a reciprocating division-plate connected with said disk so as to be moved thereby, and a guide for said division-plate associated with said disk-chamber.
